Caroline McCain, the granddaughter of the 2008 Republican presidential nominee, John McCain, is a proud member of the “Never Trump” movement. In a post published by Medium, Caroline expressed her frustrations with the new leader of the Republican party, saying that Trump lost her support when he questioned her grandfather’s “war hero” status.

In a Medium post titled, “For this Republican, Never Trump means ‘I’m With Her,'” Caroline McCain writes that she became opposed to Trump last summer when he questioned her grandfather’s status as a war hero.

“I like people who weren’t captured,” Trump said at the time.

John McCain was held prisoner during the Vietnam War.

While the Arizona senator “responded with grace and forgiveness — as only a man who was held in captivity for years can,” Caroline McCain wrote, “I’ve been nursing a grudge ever since.”

“He insulted my grandfather and attacked the very qualities — loyalty, bravery and selflessness — that he and countless other POWs embody,” she added.

McCain wrote that Trump never won her over during his candidacy, calling him a “misogynist,” “racist” and “demagogue,” citing his remarks on women and minorities throughout his campaign.

She said she decided to support Clinton during the Democratic National Convention this week, where Democratic heavy-hitters touched on themes of American exceptionalism in an effort to win over reticent Republicans.

“The party I grew up in, the party I want to work in and change and push to be more inclusive, betrayed me and countless others,” McCain wrote.

“Loyalty to party can never trump loyalty to country. And loyalty to party means nothing when the party has been poisoned.”
